Mired Indigo

#3f1b78
Notes

Mired Indigo (#3F1B78) is a deep indigo with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (263°, 63%, 29%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mired
adjective

Old Norse mýrr, mire / bog — past-participle of mire. As a color modifier, mired implies the deep-and-stuck-and-warm-brown quality of bog-and-peat-and-marsh-mud-immersion, like a Yorkshire-Moors hiker's boots after a rainy day on the saturated peat. Sits at the deep-and-warm end of the grid, parallel to peat-stained with earthy register.

Indigo
noun

Indigofera tinctoria, the South Asian legume whose leaves yield the deep blue dye that has clothed humanity for at least four thousand years — Egyptian linen, Mayan textile, the slave-grown plantations of Carolina. The color refers to a freshly indigo-dyed cotton thread: a saturated, slightly violet-shifted deep blue with the slight lustre of a fiber surface oxidized in air. Deeper than cobalt, cooler than royal.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
